boring-api · geo — Point-in-Polygon is a paid API for AI agents from geo.boring-api.com, paid per call via x402, $0.0005/call, status unknown (last checked 2026-09-13).
Determines whether a given geographic point falls inside a GeoJSON Polygon or MultiPolygon, computed entirely in-Worker with no external API calls.

How this service works
Pure-library spatial math and timezone lookup. Distance, bearing, polygons, point-in-polygon, timezone-by-coords. No external API calls — all computed in-Worker.
Output
A JSON object indicating whether the given point is contained within the provided GeoJSON Polygon or MultiPolygon geometry, computed purely in-Worker without any external API dependency.
Example use cases
Delivery zone boundary check
“Can you check if the customer's location at latitude 51.5074, longitude -0.1278 falls inside our delivery zone? I'll give you the GeoJSON polygon for our service area — just tell me if we can deliver there.”
Geofence alert for fleet
“One of our drivers is currently at latitude 37.7749, longitude -122.4194 — can you tell me if that position is inside the restricted zone polygon I have in GeoJSON format? We need to trigger an alert if they've crossed into it.”
Validate property in district
“I have a property at latitude 48.8566, longitude 2.3522 and I need to know if it falls within this GeoJSON MultiPolygon representing a specific tax district boundary — can you run that check for me?”

Endpoint
POSThttps://geo.boring-api.com/point-in-polygonWhen to prefer
Choose this endpoint when you need a fast, cheap, serverless point-in-polygon computation with no external API dependency — ideal for geofencing checks, boundary validation, or spatial queries where you already have a GeoJSON polygon and just need to test containment. At $0.0005 per call it's cost-effective for high-frequency checks.
Side effects
- Invalid or malformed GeoJSON Polygon/MultiPolygon returns an error
- Missing 'point' or 'polygon' field in request body returns a validation error
- Unsupported geometry type (e.g. LineString instead of Polygon) may return an error
- Coordinates outside valid WGS84 range may produce unexpected results
